Re: [NTG-context] How to use "fontsampler example" with Persian font

In ConTeXt, use \definedfont[font-name*arabic] instead of the following two
commands:

\font\myfont=blah blah
\myfont

Re: [NTG-context] How to use "fontsampler example" with Persian font

2016-10-07 Thread Mingranina Gingranina 
 Dear Mohammad,
 Hi,

 Thank you very much for your reply. I forgot to mention that I had
modified the fontsampler codes so that I can use it in ConTeXt with
Dabeer module.

 However, inspired by your reply I could get it to work in LuaTeX but
not in ConTeXt with Dabeer module.

 Are there any other set of features that I can test?

 Thanks,
 Mingranina

No. Flattening PDFs means to "burn in" comments and the contents of form fields 
from editable to page content.

The only way to "protect" contents from editing are the password settings. 
There are free tools to set them, but AFAIK no open source tools except maybe 
libraries.
There’s also pdfcrack to find out passwords.

Not at all.

I don't know much about fontsampler but the commands you list here are
mostly irrelevant.  My guess is you will need to set the features in the
font to get proper shaping.  A good set of features that should do the
trick is called "arabic".

When loading the font, you should do something like the following, but I
have not tried it myself.

\font\myfont=file:font.otf:language=dflt;script=arab;ccmp=yes;init=yes;medi=yes;fina=yes;rlig=yes

[NTG-context] How to use "fontsampler example" with Persian font

2016-10-07 Thread Mingranina Gingranina 
Dear All,
 Hello,

 I am trying to use "fontsampler example" with Persian fonts (please
see below or "http://wiki.luatex.org/index.php/Fontsampler;
 for fontsampler codes).
 The problem is that Persian words apears as a string of separate
glyphs, for example I get "ح‌س‌ن" instead of "حسن".
 Do I have to use commands like the followings inside \directlua or
tex.tprint to fix the problem? If yes, how can I do that?

\installlanguage [fa][default=pe,date=\longjalalidatefmt]
\mainlanguage[fa]

\definefontfeature[tlig][tlig=yes]
\definefontfeature[slanted][slant=.2]
\definefontfeature[dlang][language=dflt]
\definefontfeature[flang][language=far]

Thanks
Mingranina

[NTG-context] How do I compile a "flat" pdf?

2016-10-07 Thread Bomber K. 

Hi guys,

I am trying to create a pdf which contains some graphics that I created. 
I want to pass my PDF digitally but I don't want users to be able to 
right-click on a gfx and save it. I think this is called "flattening".
Is there a way in CTX to create such a file or do I have to recompile 
the PDF with 3rd party software?
Is there maybe even a way to flatten only specific objects like, only 
one picture of many or all, and leave form fields unflattened?


Thanks, Sebastian

[NTG-context] "marking=one" with marks on more than the first page

2016-10-07 Thread Pablo Rodriguez 
Hans,

the following sample puts the cut marks on each page:

\showframe
\setuppapersize[A5][A4]
\setuplayout
[marking=one,
location=middle]
\starttext
\ctxlua{for i=1,10 do
tex.print("\\startpagemakeup\\filterpages[setup-en.pdf][" .. i ..
"][width=0cm]\\stoppagemakeup") end}
\stoptext

Page makeups is the only way I have to get full pages imposed. But with
those, "marking=one" doesn’t work.

Is there a way to solve this?

Many thanks for your help

Pablo
